John Rock-Abolitionist

From Wikipedia:

John Rock (October 13, 1825–December 3, 1866; also John Sweat or John Swett Rock) was an American teacher, doctor, dentist, lawyer and abolitionist who originated the notion of “black is beautiful.” [1] Rock was one of the first African American men to earn a medical degree.[2] In addition, he was the first black person to be admitted to the bar of the Supreme Court of the United States.[2] With a keen passion for knowledge and an incessant fight for the equality of blacks, John Rock was destined to become one of the most distinguished and educated men of his time.
